1983–84 Birmingham City F.C. season

The 1983–84 Football League season was Birmingham City Football Club's 81st in the Football League and their 49th in the First Division. They finished in 20th position in the 22-team division, so were relegated to the Second Division for 1984–85. They entered the 1983–84 FA Cup in the third round proper and lost to Watford in the quarter-final. In the League Cup, after defeating Notts County in the third round only after three replays, they lost to Liverpool in the fourth round after a replay.

Mick Harford was the club's top scorer with 15 goals in all competitions; if only league games are counted, Harford and Howard Gayle were joint leaders with 8. The highest attendance, of 40,220 against Watford in the FA Cup sixth round, was the last 40,000 crowd seen at St Andrew's, as of 2012; the ground capacity was reduced to around 30,000 when the stadium was converted to all-seater in the 1990s.
